How To: Re-Enable Jailbreak/Unlock for Mac OS X 10.5.6

So you say you updated to the latest Mac OS X 10.5.6 and wanted to jailbreak or unlock. Well the update severely hindered your ability to do that. The Dev-Team says it is a simple kernel bug and not a specific countermeasure by Apple, never the less, there is still a work around.

It's a pretty straight forward fix actually, first you need to have administrator privileges. Then download the script file . Got it? Good, now continue on for the detailed instructions after the break!

How To: Re-Enable Jailbreak/Unlock for Mac OS X 10.5.6

i tried it and it worked then when i restarted my macbook pro and then the keyboard and mouse did not work, nor the cd drive. had to reinstall at the mac store with an ext. drive. But that might have just been a special case. For clarification it was a previous gen macbook pro not the new one that everyone claims doesnt do the jailbreaking.

Is this intended for the new Macbooks? I have a new MacBook and really want to jailbreak my iPhone but have shyed away from it because of the DFU problems people have been having. But if this fixes it awesome.

I tried running this on my macbook pro, and it asked for my password twice as expected, but then the activity bar on the top disappeared and it seemed like it just stopped doing anything... waited for a few minutes and nothing happened at all... afterwords i tried to reopen the software and try again but after i push the ok button at the readme screen it crashes. help?

Yeah, same happened to me.
I opened it and it asked for password, then it like crashed. I restarted my computer and the DFU mode still doesn't work. I tried doing it multiple times but still didn't work. What really confused me is there is a backup folder thing on my desktop like there is supposed to be, but overall it doesn't work.
WHEN IS THE DEV TEAM GOING TO COME UP WITH A SOLUTION TO THIS?

Hi,
I followed the above steps. After I accept the terms of use, it asks me for my password and then something runs in the background (I see status updates next to my time machine Icon on the task bar) and then it stops and nothing else happens. I don’t get the “Updating Boot Caches” message.
I tried to go through the terminal to the path where its supposed to copy the new files, and those files aren’t there.
Any idea on what could be missing? I really want my iPhone back :(
Thanks.

how do you re-install OSX and does it take long, I'm weighing up the risk of a non-working MacBook against a jailbroken iPhone 3G which will void my warrantee. I have to say, doesn't sound appealing...

**********WARNING!!!*****************
DO NOT DO THIS IF YOU ARE RUNNING MAC OS X FROM A POWERMAC G5 (PPC)!!!! IT RENDERS YOUR USB DRIVES USELESS, WHICH WILL KILL YOUR KEYBOARD AND MOUSE! YOU WILL HAVE TO REINSTALL FROM THE DVD.

I screwed up my iMac now too. None of the USB ports work. Is the only way to save my mac by reinstalling OSX? And if so how do I do that without using a keyboard or mouse? And will that get rid of all my saved files and programs on the mac? PLEASE HELP!!

Yeah, tried this too, no Updating Cache window appeared, have rebooted without any apparent problems(Fingers crossed) - doesn't appear to have done a thing, I get the impression no one gives a sh*t either.... just another dodgy script.

Same USB freeze on my ppc powermac g5. I lost my Tiger disk years ago. Can anyone point me in the direction of how to install (without keyboard or mouse)? I can boot up in safe mode using a leopard disk for my MacBook pro came with and keyboard mouse work fine - I can even open Disk Utility but don't know why to do there - should I get some sort of disk image that will fix my USB drive? Like an idiot I didn't backup so where would I find? Can I steal it from an iMac or PowerBook Pro install disk? Thanks in advance!!!!!!
